Abstract

1. A heat exchanger, especially for a gas or oil heated water heater, comprising at least one outer tube (11) conducting a first heat transfer medium and through which extends at least one inner tube (31) smaller in diameter for a second heat transfer medium which is in heat exchange relationship with the first transfer medium and further comprising means arranged at the periphery of the inner tube (31) for the clearance-free retention and guiding of the said tube within the outer tube (11), characterised in that, the means for the clearance-free retention and guiding of the inner tube (31) are formed by a rail (60) provided separately from the said tube and which forces the inner tube (31) unilaterally against the inner wall of the outer tube (11).
